ToaZ Z whom it may concern:

Be it known that I, CLIFTON F. LEATHER.-

BEE, a citizen of the United States, residing atNewton, in the county of Middlesex State of Massachusetts, have invented; oer tain new and useful Improvements in Coating Apparatus, of which the following -is a specification.

The present invention relates toimachines, for applying liquids and .fluidsof-various kinds to the surfaces ofmaterials of various contours,- and more especially to the provision of an improved form of apparatus. which may be used to subject flooring, strips of molding, cross arms, and

like strips or lengths of moving material to the application of paint, stain,.varn1sh,

creosote and other finishing or preservative substances, to coat them with insulation,

and simultaneously to remove any excess of the applied substance and polish and finish the treated article. I r

The principal objects of my present; in-

vention are the provision of a machine characterized as above noted, which is adapted to treat the material speedily and inexpensively and to apply the substance used with great facility and thoroughness to all the surfaces of material of irregular contour,

such as wainscoting, electric wiring conduits and the like; to provide feed regulating means whereby, when desirable, a minimum amount of the treating substance may be supplied to the applying means to provide means whereby any excess of material fed to the applying means may be removed from the machine and returned to the supply tank and used again to avoid loss, as well as certain further objects hereinafter more fully to appear. 7 p j The present application is directed particularly to thefeatures of the coating apparatus, the drying apparatus, the feeding mechanism, and the conveyer forming the subject matter of my co-pending application Serial No. 553,330, of which the present application is a division,- and of other divisions of said application -namely Serial 1 Nos. 577,626 and 577,625. V

In the attainment of the objects Lbove set forth, together with additional advantages to be disclosed below, I have provided a construction, a preferred embodiment of drawings wherein -v Fi ure 1 is a side which is illustratedj' in the acoompanyin g I elevational view,:partly in section, illustratingfthe feeding fluid ap- Referringv now more particu E A s PAIrma ra onnrcn ted e- 19, 191.6.- 7 Original application filed April 4,, 1 110," serial at. 553,330.

In order that the increase'of cost and; loss of time incldent to rehandling the material after leaving theplaner, may be saved and to insure a direct feed -o f such material through the machine without; lateral displacement, it may be fed bythe live rolls of the planer; otherwise such feed may be ected v y th ppos t ly disp sed live vrolls v 23 and 24 driven from the motor 25 through the gearing to be hereinafter described. A stationary guide block 26 and a spring guide 27 disposed oppositely thereto 'andcooperat ing therewith are located -closelyadjacent the rolls 23 and 2-it'to insure the alinement of the material as it'is fed; throughthe machine,-

A roll 28 is provided for the initial support of the fed material, and as it pass s the rolls 23 and 24 it is successively engaged byrthe singleidler roll 30, and thepairs of live .rolls 3 l,32, and 33, 35% adapted to hold it in contact with thebrushdevices 35,3 6,. 37 and 38, designed respectively for applying he q id, fo r bing it n, f r W pm'g a y x ess romth e ges f the'm t ri ls a d for removingany vestigesfrom the face.

thereof. I .7 Un viewing Fig. l particularly it will b observedthat I mount in the framing 20 the rotatable brush 35, movable vertically to the end that compensation may be made for wear in service by means of its suspension in the outer ends of the yoke 40 whose shaft is pivoted in the casing as indicated at 41, 41, one of said ends being provided with an adjusting screw 42. V F or the purpose of furnishing a supply of ti'eating liquid to the brush 35', I make use 'ing forms a drip pan for the several brushes and a drain pipe 56 continuously open to the tank 46 is provided to convey thereto any excess liquid that may perchance fall upon 7 such pan;

For driving the pump 45, the brush 35, and the rolls 24, 32 and 34, in unison, to the end that a uniform application of liquid may be had, I mount on the shaft of the motor 25a pulley 60 driving by means of a belt 61 the pulley wheel 62 which is mounted on the shaft 63 carrying the roll 34. The opposite end of the shaft 63 is provided with a gear 65 which by means of a chain 66 drives the gear 67 mounted on the shaft 68 of theroll 32. The shaft 68 carries on the end, (opposite to that carrying the gears 67 and 69), a'gear 73 driving, by means of the intermediate gears 74 on a shaft 74*, and 75 on the shaft 76, the gear 75 on the shaft 76 carrying the roll 31. At the end of said shaft 7 6 is mounted a sprocket wheel 77 driving by means of the chain 78 the pump 45. On the end of the shaft 72 opposite the sprocket 71 is carried a gear 79 which through intermediate gears 80 on the shaft 80, and 81 on the shaft 82 drives the gear 82 on the shaft 83 carrying the roll 23. Upon said shaft 82 is mounted a pinion 83 diving through the chain 84 the sprocket 85 on the shaft 86 carrying the brush 35.

In order that the upper rolls 23, 30, 31 and 33 may be adjusted axially to accommodate materials of differing thicknesses, and that they may be conveniently removed where desirable,'I preferably mount them in the opposing members of pairs of boxes 88, S9, 90 and 91 pivoted to opposite sides of the framing 20, each box being provided at its free end with an adjustable screw device 92 having engagement with an extension of the box and insertedand having threaded engagement in a socket formed'in theframing. Springs 92-92 under a certain degree of compression are mounted upon the said screw device 92 on both sides of said extension in order to compensate for any slightunevennesses in the material.

Inasmuch as I have designed themachine illustrated as an embodiment of my present invention primarily for the purpose of em ploying a highly volatile treating compound to flooring, the respectivesizes of the pulley 77 and 77 by which the pump is driven through the belt 78, should be so proportioned that as closely as possible the precise amount of liquid that may be taken up by the brush 35 be delivered upon the spreader plate 50, in order to avoid any accumulation upon the drip pan 55 or the rolls. As a further precaution againstspattering of the liquid, or throwingthereof from the brush 35, I'provide such brush with a cover 35", open at the top, and supported by the shaft 86 and yoke 40. This is especially desirable since my improved machine is used with great economy for the treatment of flooring as it issues from the planer, and such locations usually presenta considerable amount of dust, chips, shavings and other highly inflammable substances.

To insure that the liquid as it is ejected from'the pipe 48 is distributed evenly over the spreader plate 50,- I mount on the open end of the pipe a striking plate 48 which also serves the further purpose of preventing any spattering of the fluid on the brush 35 or the framing 20 and thus prevents accumulation thereon of the heavier residue held in suspension in the volatile fluid of such paint. As a further guard against accumulation of residual material I provide the rolls 30, 31 and 33 with shields 30 31 and-33 Each of the stationary brush devices and 38 is vertically adjustable by means respectively of the'screw devices 95, 96 threaderally by the screw members 97 97 threaded ried in a frame36 for the sake of convenience in replacement and in order that unequal wear of the several parts may be cared for without discarding unworn porneoarzv 1 A tions), I provide the cooperating spring devices comprising the laterally pressing,

' oppositely disposed springs 100, 1 adjustvolving brush 88 mounted in bearings 10,5, 105 carried by the arms 106, 106 of the yoke s 107 pivoted in the framing20 as indicated at 108, 108 and adjustable vertically by the,

7 screws 109 threaded into the framing as indicated at 110 at each side thereof,,sustaining such bearings. The brush 38 is driven from the shaft 63 by means of a pinion 105 connected to the sprocket 106 on the shaft 107 carrying such brush, by a chain 108 In the present device, as in that of Figs. 1 to 3, the roll33 is drivenby means of ,the

gears 111 carried on the-shaft63', the intermediate gears 112 and 118. on shafts 112 and 113, and the gear 114 mounted on the shaft 115 of said roll 33. In the device of Figs. 4: and 5the roll 34 serves not only as partof the means'for sustaining and feeding the material through'the machine, but also for the purpose of removing from. the brush 38 any liquid that may have accumulated thereon ensuant upon the progress of material -through the machine, and over such brush, whereas in the device of Figs. 1 to 3, the roll tserves the sole purpose of sustaining and feeding such material.

Having thus described my invention and illustrated its use, what I claim as new and desire to secure by Letters Patent is the following: 7 V
